GAS-HEATED STEAM RADIATOR.

Application filed May 10, 1927. Serial No..190,308.

The present invention is concerned with therprovision of a radiator inwhich gas is used as a heating medium. Part of the heat generated by thegas acts directly on the exterior walls of the radiator and part of theheat generated is transferred through the interior walls of the radiatorto abody of w ter completely surrounding the burner chamber Steam isthus generated on the interior. of the radiator and an exceedinglyeflicientheater is provided dueto the combined heat action of the steamandgas.

One feature of the invention is the pro vision of a radiator of thischaracter in which the common inconvenienceand disadvantage of highlyheating the floor 'beneath the radiator and the wall behind it, isentirely overcome, and substantially all of the heat. generated isradiated upwardly and outwardly into a room.

Burning or highly'heating the floor is prevented bythe use of the bodyof water which completely encircles the burner chamber. The products ofcombustion and hot gases from the burner escape through vents betweenthe radiator sections, and baffle means is provided which throw suchvapors forwardly into the room, effectively preventing them fromscorching or overheating a wall behind the radiator. The radiator ispreferably thermostatically controlled in any convenient or conventionalmanner so that a uniform temperature may be maintained.

Another object of the invention is to provide a radiator which may havethe attractive appearance of an ordinary steam or hot water radiator,and will involve the use of no conspicuous structural features whichmight detract from its attractiveness.

Other and more general objects of the in.- vention are to provide aradiator of simple, 'practical construction which will be rugged,durable and efficient in use, and well suited to the requirements ofeconomical manufacture.

With the above noted and other objects in view, the invention consistsin certain novel features of construction and combinations andarrangements of parts, as will be more fully hereinafter set forth andpointed out in the claims. The invention may be more fully understoodfrom the following description in connection with the accompanyingdrawings, wherein:

Fig. 1 is a view partly in front elevation and partly in verticalsection through a radiator embodying the present invention.

2 is a vertical sectional view on the line 2 2 of Fig. 1.

1g. 3 1s a sectional plan view of the burner and 1ts associated parts.

Figs. 4 and 5 are plan, views of the two end closure plates for theburner chamber.

The radiator of the vpresentinvent-ion as stated above very closelyresembles in exvertical sections,-each section includingthree spacedhollow columns 10 connected by upper and lower chambers 11, '11. The endsections of the radiator may include supporting legs 12 and the sectionsare connected by push nipples 13 entering aligned tapered openings 14 aswell as bythe usual connecting tie bolts '15.

The cast sections are provided with cylindrlcal passageways 16intersecting the lower chambers 11 and these passageways align tocooperatively define a burner chamber 17 within which is mounted alongitudinally extending burner consisting of the, tube 18 and theaperturedplate '19.

The lower portionzof the radiator contains water, the water level beingalways high enough to result in completely surrounding the burnerchamber so that heat from the walls of the cylindrical passageways 16will be transferred to the water and cause the generation of steam.

The burner chamber is provided with openings 20 between the adjacentradiator sections and the escaping hot gases and products of combustionare directed upwardly and forwardly by integral baffling flanges 21carried by the sections. The flanges of the adjacent faces of adjacentradiator sections cooperate, as best seen in Fig. 1, to define baffleplates which prevent the hot gases escaping from the vents 20 fromplaying directly on a wall behind the radiator.

A valve. such as 22 may control the flow of gas to the pipe 18, and anyconvenientor conventional thermostatic means such as that indicated at23, may be utilized to control the gas flow.

The ends of the burner chamber are closed by plates 24: and 25 providingmounting for the burner pipe 18 and means of attachment for the gasconnections, thermostat etc. conventional safety valve may be providedat 26, and water introduced into 'ternal appearance a standard type ofsteam radiator bemg built up of a plurality of the radiator through afilling opening at 27.

From the foregoing description, it will be seen that I have provided aburner of a type which is highly efiicient in so far as the heatobtained from a given amount ofgas is con-' down in the chamber, and theflames do not impinge directlyon the walls of the vent openings.

There are no parts of the radiator which may burn or corrode, and inconsequence the cost ofrepair and maintainance is slight. The radiatormay be operated on any kind of gas, such for instance as illuminatinggas, fuel gas, and natural gas.

This radiator is provided with the usual connections (not shown) so thatit may be used in combination with a straight steam or hot waterradiation system without making any alterations in the heater. Thus thedevice may function either as an independent unit or in connection withan ordinary system.

Various changes and alterations might be made in the general form andarrangement of parts described without departing from tions,

the invention. Hence I do not wish to limit myself to the precisedetails set forth, but shall consider myself at liberty to make suchchanges and alterations as fairly fall within the spirit and scope ofthe appended claims.

I claim:

1. A gas heated steam radiator comprising a plurality of spaced andconnected sections adapted to contain water in their lower poratransversely extending burner cham her in the lower part of the radiatorand so located therein that it will be surrounded by Water, a gas burnerin the chamber, said 7 chamber having openings in the top between theradiatorsections for the passage of the products of combustion, andbafiles extend,- ing upwardly and forwardly from thechamber adjacent theopenings therein between the radiator sections for directing the prod,-ucts of combustion passing through said openings. 7

2. A gas heated steam radiator comprising a plurality of spaced andconnected sec:

tions adapted to contain water in their lower portions, each radiatorsection having a cylindrical passage adjacent its lower end, saidpassages forming a transversely extending burner chamber and havingtheir adjacent ends cut away to form openings in thetop of the chamberbetween the sections, said burner chamber being so located in theradiator that it will be surrounded by water, a burner in said chamber,and plates secured to the radiator at the ends of the chamber and inwhich the burner is mounted.
